Abstract: A starter with an intermediate gear includes a front bearing portion formed with a mounting hole for supporting the front end portion of an intermediate shaft and a retaining hole located at a position offset from a center of the mounting hole in a radial direction in such a manner as to intersect the mounting hole, and a screw member threaded into the retaining hole and remaining in engagement with the intermediate shaft to retain the intermediate shaft in a fixed position against removal from housing.

Abstract: An alloy for a lead member is used for an electric lamp having a metal/vitreous material interface. Molybdenum or tungsten serving as an electric lamp current conductor is used as a base for the lead member, wherein the molybdenum or tungsten contains titanium oxide or other oxides. Automotive bulbs use this alloy for a lead member.

Abstract: An organic EL element with high luminous efficiency is manufactured by fabricating a compound substrate by forming a microscopic unevenness on a transparent substrate of glass or the like using a sol-gel material and a nanoimprinting method, applying a high refractive index material on the microscopic unevenness, and planarizing the surface, and layering a first electrode, an organic solid layer including an organic light-emitting material and a first electrode in that order on the compound substrate.

Abstract: A method of manufacturing a yoke includes a step of cutting a steel plate into a rectangular sheet having a plurality of first dovetail convexities at one end thereof and a plurality of second dovetail convexities at the other end, a step of rolling the rectangular sheet into a cylinder to fit the first dove tails and the second dove tails to each other and a step of punching border portions of the first dove tails and the second dove tails. The second dovetail convexities are formed to be the same in shape as the first dovetail convexities so that they can fit to the first dovetail convexities. A smooth-faced yoke can be manufacture without using an expensive welder.

Abstract: In an electromagnetic switch of a starter, a bobbin has two terminal holders on a flange. Each of the terminal holders defines a slot on its end surface and a terminal is press-fitted in the slot in an axial direction of the bobbin. An end of an excitation coil wound around the bobbin is pulled out the bobbin and connected to the terminal. A molded cover provides a through hole and is mounted on the terminal so that the terminal passes through the through hole. A sealing member is press-fitted on the terminal to air-tightly seal the through hole. A rod cover fitted on a rod supporting a movable contact has slits on its cylindrical part in the axial direction. The slits are closed before a distal end of the cylindrical part.

Abstract: A center case has a force-receiving wall and a fixed wall, and is rigidly fixed in a starter. A gear-forming section is coaxially arranged with the center case, and has a forcing wall and a movable wall on the side of the center case. A cushion member is elastically received between the force-receiving wall of the center case and the forcing wall of the gear-forming section. The fixed wall of the center case and the movable wall of the gear-forming section are arranged to have a gap, and oppose each other. When an excessive torque works on the gear-forming section via an internal gear, the cushion member absorbs an impact force to move the movable wall by a predetermined distance. In this case, the movable wall contacts the fixed wall so that a compression rate of the cushion member can be restricted.

Abstract: A starting apparatus for starting an engine has a drive motor and a reduction gear. The reduction gear includes a shock absorbing member and restricting members. The shock absorbing member is provided to elastically receive a reaction force exerted to an internal gear. The restricting members are provided to restrict a compressed amount of the shock absorbing member by making contact with each other. When bringing into contact with each other, the restricting members make contact at the outside diameter portions thereof. Accordingly, unpleasant noise generated during the operation of the starting apparatus is reduced by the shock absorbing member. Further, the damage to respective parts is reduced.

Abstract: A starter for engines uses a leaf spring as a shaft lever for advancing a pinion gear for engagement with a ring gear. The shift lever may be constructed with a plurality of layered leaf springs having respective front ends spaced apart one another to contact a one-way clutch at different positions. The shift lever may include a lever holder which has a low heat conductive member to minimize fatigue of the leaf spring. The leaf spring is initially loaded with a spring force.

Abstract: A high-pressure discharge lamp comprises a lamp tube made of quartz glass and having a central portion formed in a spherical shape, and a pair of opposing tungsten electrodes inserted into the lamp tube. At least one of the tungsten electrodes is made of a tungsten material which contains more than 10 ppm of one of Co and Ni, or 10 ppm of Co and Ni in total, or a tungsten material which contains 20 ppm or more of at least two of Fe, Co and Ni in total, or a tungsten material which contains 20 ppm or more of Fe. Fe, Co and Ni belong to iron-group metals. The inter-electrode distance, i.e., distance between the leading ends of both tungsten electrodes is set to approximately 1-2 mm or less.

Abstract: A process for preparing a vitamin D derivative including providing an ultraviolet irradiation apparatus for photochemical reactions, which has an ultraviolet radiation-emitting lamp, an optical system which receives light from the ultraviolet radiation-emitting lamp and emits ultraviolet rays having a specific wavelength, and a quartz rod which receives the ultraviolet rays having the specific wavelength from the optical system and emits the ultraviolet rays, irradiating a solution of a provitamin D derivative with the ultraviolet rays emitted from the quartz rod to cause a photochemical reaction to the provitamin D derivative solution, thereby forming a previtamin D derivative, and subjecting the previtamin D derivative to a thermal isomerization reaction to prepare the vitamin D derivative.

Abstract: A brush of a rotary electric machine includes a brush element and a pigtail. The brush element includes a high-conduction member extending in the longitudinal direction and a low-conduction member bonded to a side of the high-conduction member. The low-conduction member is a thin layer extending in the longitudinal direction from the contact surface to the middle of the length of the brush element. The wire end is embedded in the high conduction member on the side of the low-conduction member remote from the contact surface.

Abstract: A shock absorber for a starter is presented. The shock absorber includes a rotary disk, a stationary disk and a disk spring. The rotary disk is pressed by the disk spring against a stationary disk to generate frictional force when the rotary disk is rotated by an excessive shock thereby absorbing the shock. The rotary disk has a plurality of press-formed rectangular dimples at a surface opposite the stationary disk, and each side of each the rectangular dimple inclines to a direction of rolling of the raw material of the rotary disk.
